Cynthia Zaken-Pavlecic, 51, and her mother, Mary Zaken, 88, both of Elizabeth, Pa., were killed in the crash early Monday morning.

The Ohio County Sheriff's Office said Zaken-Pavlecic was driving when the car entered the westbound lanes at the Dallas Pike ramp going the wrong direction and hit a tractor-trailer at about 3 a.m.

“What we don't know is why they were here, where they were in this area and where they were coming from before the crash occurred,” said Sheriff Patrick Butler. “Whether they got off and got gas, stopped and got something to eat at a truck stop, we don't know that.”

Charlie Morton pitched five-hit ball for seven innings, Neil Walker hit a review-aided home run and the Pittsburgh Pirates beat the Cincinnati Reds 3-0 Sunday in a testy game in which benches cleared after All-Stars Andrew Mcutchen and Brandon Phillips were hit by pitches.
